Smokey turbo

[newageredneck]

Having a problem with the Supra I bought this month, 1989 Turbo. Old family friend who sold it to me explained and demonstrated. When the car turns over and starts, after maybe five seconds there will be moderate white/blue mix of smoke from the stock exhaust. Not steam or wispy smoke like that of blown head gasket (hard to believe BHG due to the fact that it's apparently a JDM 7MGTE with <30,000 miles not to mention I know his credibility. He doesn't drive like Fast and Furious and the problem was not an issue until sometime last fall.)

Once the car starts running, as soon as the engine revs past idle the smoke from the tailpipe increases and much more smoke begins to come from under the hood, particularly the turbo.

Hoping I don't have a shot motor and it's something I can fix myself
